Class Information
Number: 72/86
Name: Metal deforming > By use of tool acting during relative rotation between tool and work about internal center (e.g., gyrating or rotating tool) > During rotation of work > Using angularly related roller-couple acting parallel to axis of work rotation
Description: Subject matter including a roller couple* wherein the axes of the rollers of the roller couple are not parallel to each other, and wherein the roller couple is particularly adapted to opposingly engage the radial surfaces of a rotating disklike workpiece such that during metal deformation, the deforming forces of the rollers on the work are opposed to each other and are parallel to the work axis.
